Cool... Europa Universalis looks nice.
Final Fantasy and Diablo 2... sorry, me not like any of them.
That mod for Crysis sounds interesting.
Shogun 2 is on the list.
John Defoe Tetrology - You're kidding, right? Not -that- old.
Ok, "old" as in post-2008... that's what I meant when I said it.
If you value story over everything else then it's almost
a given that you at least try the Cult-Classic "Planescape: Torment."
It holds the title of "Best story and writing for a computer game EVER!"
It's built around the old Balder's Gate engine so it may seem dated but
that doesn't stop it pulling you in, in any day and age.
Alternatively I would also recommend "Arcanum of Steamworks and
Magick Obscura."
Awesome steam-punk with epic story.
There are tons of others I could probably think of but these stand out
to me as I read your post.
